    Abstract: A one-time password system capable of defending against on-line phishing attacks. The one-time password system is composed mainly of a Java smart card, a pre-end password calculation module, a post-end password registration module, a post-end password verification module and a post-end database. In the system, a Java smart card is used and message authentication code technology is relied upon to associate a login URL with a one-time password generation process, so that a user identification process against on-line phishing attacks can be achieved.
